------------------------------------------------------------------------ - OpenBSD 3.5 RELEASED ------------------------------------------------- May 1, 2004. We are pleased to announce the official release of OpenBSD 3.5. This is our 15th release on CD-ROM (and 16th via FTP). We remain proud of OpenBSD's record of eight years with only a single remote hole in the default install. As in our previous releases, 3.5 provides significant improvements, including new features, in nearly all areas of the system: - Ever-improving security (http://www.OpenBSD.org/security.html) o New ptm device (see pty(4)) that allows non-privileged processes to allocate a properly-permissioned pty. As a result any process can now open a pty easily, meaning xterm(1) and xconsole(1) are no longer setuid root. (In 3.4 they were setuid root, but privilege revoking). o malloc(3) chunk randomization and guard pages. This helps to detect out-of-bounds reads and writes. o Privilege separation added to allow complex operations to occur in an untrusted, unprivileged process, resulting in much greater security for the following processes: - isakmpd(8) - named(8) (Previously privilege revoking, but this had a small breakage). - pflogd(8) - tcpdump(8) o Many improvements and bug fixes in the ProPolice stack protector. Several other code generation bugs for RISC architectures were also found and fixed. - Improved hardware support (http://www.OpenBSD.org/plat.html) o New hardware platforms: - OpenBSD/amd64 Supporting the AMD64 architecture natively, with full 64-bit support, 8 extra registers in the architecture to significantly increase performance, and a memory management Non-Executable bit that permits full W^X support. - OpenBSD/cats Our first entry in the ARM-cpu landscape. We intend to use this as a development platform for something else we plan for the future... - OpenBSD/mvme88k Supporting an older, but very cool cpu architecture, perhaps the most pure RISC cpu ever. o The hppa architecture gets support for many PCI based machines with the addition of dino(4) GSC-PCI bridge. o New oosiop(4) driver for NCR 53C700 SCSI host adapters. o Major improvements to ahc(4), bringing support for many new models. o New bce(4) driver, supporting the Broadcom BCM4401 FastEthernet chipset. o New mpt(4) driver for LSI Fusion-MPT SCSI and FibreChannel host adapters. o New snapper(4) audio driver for recent iBook (since May 02) and PowerBook (since Apr 02) models. o Improved stability of the wi(4) driver as well as support for USB-based adapters and software WEP. o wi(4) in HostAP mode now supports SSID hiding in newer prism firmware revisions. o Fixed several firmware incompatibility issues in an(4). o Improved ATA and SATA support. o Support for i835 AGP GART in vga(4). o Improved Gigabit Ethernet support for em(4), sk(4) & bge(4). o Several fixes for apm(4). o Support for Intel 852/855/865 AGP chipsets. o SCSI(4) improvements: - Bus probe made faster by skipping non-existent LUNs. - Bus probe made saner by elimination of spurious commands. - Bus probe made safer by having INQUIRY commands ask only for available data. - Eliminated a race that, e.g., caused problems burning CDs at high speeds. - SCSIDEBUG output can now be restricted to specified buses. - ASC/ASCQ diagnostic messages updated to SCSI-3 standards. - Better error handling. o Many more USB Flash and other umass(4) devices work as a result of SCSI improvements. o hw.setperf sysctl allows controlling the speed of many new i386 cpus, great for prolonged battery life.. - Major improvements in the pf packet filter, including: o Atomic commits of ruleset changes (reduce the chance of ending up in in an inconsistent state). o A 30% reduction in the size of state table entries. o Source-tracking (limit number of clients and states per client). o Sticky-address (the flexibility of round-robin with the benefits of source-hash). o Invert the socket match order when redirecting to localhost (prevents the potential security problem of remote connections being identified as local). o Significant improvements to interface handling. - New tools for filtering gateway failover: o CARP (the Common Address Redundancy Protocol) carp(4) allows multiple machines to share responsibility for a given IP address or addresses. If the owner of the address fails, another member of the group will take over for it. A discussion of the history of CARP can be found here. o Additions to the pfsync(4) interface allow it to synchronise state table entries between two or more firewalls which are operating in parallel, allowing stateful connections to cross any of the firewalls regardless of where the state was initially created. - Performance improvements: o Improved connection/socket lookup - about 100 times faster at 10000 sockets than 3.4. o TCP SYN cache. Greatly reduces the memory cost of half-open TCP connections. o Implemented TCP adjustments recommended by RFC3390, controllable via sysctl. o OpenSSL speedup on i386, up to 100% improvement for md5, sha1, blowfish, des, 3des, rsa, dsa and bn. o OpenSSL now directly uses the new AES instructions some VIA C3 processors provide, increasing AES to 780MBytes/second (so you get to see a fan-less cpu performing AES more than 10x faster than the fastest cpu currently sold). o Directory hashing makes lookups in large directories much faster. - New features and significant bug-fixes included with 3.5 o Replacement of the GNU bc(1), dc(1), nm(1) and size(1) commands with BSD licensed equivalents. o pty(4) devices are now allocated on demand, up to a configurable limit. o The closefrom(2) system call has been added. o TCP MD5 signatures (used by nc(1) and bgpd(8)). o Network boot support for i386 and amd64, using pxeboot(8). o The i386 8GB boot loader limitation has been removed. o spamd(8) gains greylisting support. This allows greylisting (a very powerful spam reduction technique) to be done on a firewall for many mail hosts, no matter what MTA is being used. o Interface 'cloning', accessed by ifconfig(8) commands create and destroy. E.g. `ifconfig vlan100 create'. o ifconfig(8) can now be used with a generic interface name, for listing all such configured interfaces. E.g. `ifconfig carp'. o The MAKEDEV(8) manual pages are now generated, and hence, accurate. o Complete rewrite of package tools in perl. o syslogd(8) now supports logging to memory buffers, to be read using syslogc(8). This is useful for diskless or flash-based computers. o IPsec ESP in UDP encapsulation. o authpf(8) now tags traffic in pflog(4) so that users may be associated with traffic through a NAT setup. o XFS has been added to the GENERIC kernels so that afsd(8) may be started easily, eliminating the need to recompile the kernel to use AFS. o AFS can now be used anonymously by enabling it in rc.conf(8) with no further configuration. o The ps, top and w utilities no longer break when changes are made in kernel structures. o A poll interface has been added to the rpc routines in the standard C library. Use of poll over select can result in better performance for programs with a large number of open file descriptors. o dhclient(8) now detects when the interface it configured is modified and gracefully exits. e.g. repeatedly running it against the same interface leaves only the last instance active. o New tools: - sensorsd(8), monitoring hardware sensors. - procmap(1), to examine a process' memory map. - bgpd(8), implementing the BGP-4 routing protocol. - pkill(1) and pgrep(1), finding or signalling processes by name. o OpenSSH 3.8.1. o Many, many man page improvements. - The "ports" tree is greatly improved (http://www.OpenBSD.org/ports.html) o The 3.5 CD-ROMs ship with many pre-built packages for the common architectures. The FTP site contains hundreds more packages (for the important architectures) which we could not fit onto the CD-ROMs (or which had prohibitive licenses). - The system includes the following major components from outside suppliers: o XFree86 4.pre4.0 (+ patches). o gcc 2.95.3 (+ patches and ProPolice) gcc 3.3.2 (+ patches and ProPolice) on sparc64, amd64, and cats o Perl 5.8.2 (+ patches). o Apache 1.3.29 and mod_ssl 2.8.16, DSO support (+ patches). o OpenSSL 0.9.7c (+ patches). o Groff 1.15. o Sendmail 8.12.11. o Bind 9.2.3 (+ patches). o Lynx 2.8.4rel.1 with HTTPS and IPv6 support (+ patches) o Sudo 1.6.7p5. o Ncurses 5.2. o Latest KAME IPv6. o Heimdal 0.6rc1 (+ patches). o Arla-current. If you'd like to see a list of what has changed between OpenBSD 3.4 and 3.5, look at http://www.OpenBSD.org/plus35.html Even though the list is a summary of the most important changes made to OpenBSD, it still is a very very long list. ------------------------------------------------------------------------ - SECURITY AND ERRATA -------------------------------------------------- We provide patches for known security threats and other important issues discovered after each CD release. As usual, between the creation of the OpenBSD 3.5 FTP/CD-ROM binaries and the actual 3.5 release date, our team found and fixed some new reliability problems (note: most are minor, and in subsystems that are not enabled by default). Our continued research into security means we will find new security problems -- and we always provide patches as soon as possible. Therefore, we advise regular visits to http://www.OpenBSD.org/security.html and http://www.OpenBSD.org/errata.html Security patch announcements are sent to the security-announce@OpenBSD.org mailing list. For information on OpenBSD mailing lists, please see: http://www.OpenBSD.org/mail.html ------------------------------------------------------------------------ - CD-ROM SALES ---------------------------------------------------------- OpenBSD 3.5 is also available on CD-ROM. The 3-CD set costs $40USD (EUR 45) and is available via mail order and from a number of contacts around the world. The set includes a colorful booklet which carefully explains the installation of OpenBSD. A new set of cute little stickers are also included (sorry, but our FTP mirror sites do not support STP, the Sticker Transfer Protocol). As an added bonus, the second CD contains an exclusive audio track, combining the "CARP License" skit and a song entitled "Redundancy must be free". Lyrics for the song may be found at: http://www.OpenBSD.org/lyrics.html#35 Profits from CD sales are the primary income source for the OpenBSD project -- in essence selling these CD-ROM units ensures that OpenBSD will continue to make another release six months from now. The OpenBSD 3.5 CD-ROMs are bootable on the following five platforms: o i386 o amd64 o macppc o sparc o sparc64 (UltraSPARC) (Other platforms must boot from floppy, network, or other method). For more information on ordering CD-ROMs, see: http://www.OpenBSD.org/orders.html The above web page lists a number of places where OpenBSD CD-ROMs can be purchased from. For our default mail order, go directly to: https://https.OpenBSD.org/cgi-bin/order or, for European orders: https://https.OpenBSD.org/cgi-bin/order.eu All of our developers strongly urge you to buy a CD-ROM and support our future efforts. Additionally, donations to the project are highly appreciated, as described in more detail at: http://www.OpenBSD.org/goals.html#funding ------------------------------------------------------------------------ - T-SHIRT SALES -------------------------------------------------------- The project continues to expand its funding base by selling t-shirts and polo shirts. And our users like them too. We have a variety of shirts available, with the new and old designs, from our web ordering system at: https://https.OpenBSD.org/cgi-bin/order and for Europe: https://https.OpenBSD.org/cgi-bin/order.eu The OpenBSD 3.5 t-shirts are available now. We also sell our older shirts, as well as a selection of OpenSSH t-shirts. ------------------------------------------------------------------------ - FTP INSTALLS --------------------------------------------------------- If you choose not to buy an OpenBSD CD-ROM, OpenBSD can be easily installed via FTP. Typically you need a single small piece of boot media (e.g., a boot floppy) and then the rest of the files can be installed from a number of locations, including directly off the Internet. Follow this simple set of instructions to ensure that you find all of the documentation you will need while performing an install via FTP. With the CD-ROMs, the necessary documentation is easier to find. 1) Read either of the following two files for a list of ftp mirrors which provide OpenBSD, then choose one near you: http://www.OpenBSD.org/ftp.html ftp://ftp.OpenBSD.org/pub/OpenBSD/3.5/ftplist As of May 1, 2004, the following ftp sites have the 3.5 release: ftp://ftp.ca.openbsd.org/pub/OpenBSD/3.5/ Alberta, Canada (above is master site, please USE A MIRROR below) ftp://ftp.usa.openbsd.org/pub/OpenBSD/3.5/ Boulder, CO, USA ftp://ftp5.usa.openbsd.org/pub/OpenBSD/3.5/ Redwood City, CA, USA ftp://ftp7.usa.openbsd.org/pub/os/OpenBSD/3.5/ West Lafayette, IN, USA ftp://openbsd.wiretapped.net/pub/OpenBSD/3.5/ Sydney, Australia ftp://ftp.kd85.com/pub/OpenBSD/3.5/ Lovendegem, Belgium ftp://ftp.calyx.nl/pub/OpenBSD/3.5/ Amsterdam, Netherlands ftp://ftp.se.openbsd.org/pub/OpenBSD/3.5/ Stockholm, Sweden ftp://ftp.linux.org.tr/pub/OpenBSD/3.5/ Turkey Other mirrors will take a day or two to update. 2) Connect to that ftp mirror site and go into the directory pub/OpenBSD/3.5/ which contains these files and directories. This is a list of what you will see: ANNOUNCEMENT XF4.tar.gz i386/ root.mail Changelogs/ alpha/ mac68k/ sparc/ HARDWARE amd64/ macppc/ sparc64/ PACKAGES cats/ mvme68k/ src.tar.gz PORTS ftplist mvme88k/ sys.tar.gz README hp300/ packages/ tools/ SIZES hppa/ ports.tar.gz vax/ It is quite likely that you will want at LEAST the following files which apply to all the architectures OpenBSD supports. README - generic README HARDWARE - list of hardware we support PORTS - description of our "ports" tree PACKAGES - description of pre-compiled packages root.mail - a copy of root's mail at initial login. (This is really worthwhile reading). 3) Read the README file. It is short, and a quick read will make sure you understand what else you need to fetch. 4) Next, go into the directory that applies to your architecture, for example, i386. This is a list of what you will see: CKSUM bsd.rd* floppyB35.fs pxeboot* INSTALL.i386 cd35.iso floppyC35.fs xbase35.tgz INSTALL.linux cdrom35.fs game35.tgz xfont35.tgz MD5 comp35.tgz index.txt xserv35.tgz base35.tgz etc35.tgz man35.tgz xshare35.tgz bsd* floppy35.fs misc35.tgz If you are new to OpenBSD, fetch _at least_ the file INSTALL.i386 and the appropriate floppy*.fs or cd35.iso file. Consult the INSTALL.i386 file if you don't know which of the floppy images you need (or simply fetch all of them). 5) If you are an expert, follow the instructions in the file called README; otherwise, use the more complete instructions in the file called INSTALL.i386. INSTALL.i386 may tell you that you need to fetch other files. 6) Just in case, take a peek at: http://www.OpenBSD.org/errata.html This is the page where we talk about the mistakes we made while creating the 3.5 release, or the significant bugs we fixed post-release which we think our users should have fixes for. Patches and workarounds are clearly described there. Note: If you end up needing to write a raw floppy using Windows, you can use "fdimage.exe" located in the pub/OpenBSD/3.5/tools directory to do so. ------------------------------------------------------------------------ - XFree86 FOR MOST ARCHITECTURES --------------------------------------- XFree86 has been integrated more closely into the system. This release contains XFree86 4.pre4.0. Most of our architectures ship with XFree86, including sparc, sparc64 and macppc. During installation, you can install XFree86 quite easily. Be sure to try out xdm(1) and see how we have customized it for OpenBSD. On the i386 platform a few older X servers are included from XFree86 3.3.6. These can be used for cards that are not supported by XFree86 4.pre4.0 or where XFree86 4.3.0 support is buggy. Please read the /usr/X11R6/README file for post-installation information. ------------------------------------------------------------------------ - PORTS TREE ----------------------------------------------------------- The OpenBSD ports tree contains automated instructions for building third party software. The software has been verified to build and run on the various OpenBSD architectures. The 3.5 ports collection, including many of the distribution files, is included on the 3-CD set. Please see the PORTS file for more information. Note: some of the most popular ports, e.g., the Apache web server and several X applications, come standard with OpenBSD. Also, many popular ports have been pre-compiled for those who do not desire to build their own binaries (see BINARY PACKAGES, below). ------------------------------------------------------------------------ - BINARY PACKAGES WE PROVIDE ------------------------------------------- A large number of binary packages are provided. Please see the PACKAGES file (ftp://ftp.OpenBSD.org/pub/OpenBSD/3.5/PACKAGES) for more details. ------------------------------------------------------------------------ - SYSTEM SOURCE CODE --------------------------------------------------- The CD-ROMs contain source code for all the subsystems explained above, and the README (ftp://ftp.OpenBSD.org/pub/OpenBSD/3.5/README) file explains how to deal with these source files. For those who are doing an FTP install, the source code for all four subsystems can be found in the pub/OpenBSD/3.5/ directory: XF4.tar.gz ports.tar.gz src.tar.gz sys.tar.gz ------------------------------------------------------------------------ - THANKS --------------------------------------------------------------- OpenBSD 3.5 includes artwork and CD artistic layout by Ty Semaka, who also arranged an audio track on the OpenBSD 3.5 CD set. Ports tree and package building by Peter Valchev, Nikolay Sturm and Christian Weisgerber. System builds by Theo de Raadt, Henning Brauer, and Miod Vallat. ISO-9660 filesystem layout by Theo de Raadt. We would like to thank all of the people who sent in bug reports, bug fixes, donation cheques, and hardware that we use. We would also like to thank those who pre-ordered the 3.5 CD-ROM or bought our previous CD-ROMs. Those who did not support us financially have still helped us with our goal of improving the quality of the software.
